IMPROVEMENT IN OIL-CUPS.

Specification forming part of Letters Patent No. 221,928, dated'November 25, 1879.; application tiled August 27, 1879.

To all lwhom it may concern.-

Be it known that I, JOHN G. MCBRIDE, of the city of Sacramento, State ofCalifornia, have invented a new and useful Improvement in Oil-Cups, ofwhich the following is a specication.

The invention relates to that class" of oilcups used for journals andbearings where a constant and uninterrupted iiow of oil is required.

Y The invention consists in the use of a spring to support the.feeding-wire and prevent its bearing upon the journal.

In the accompanying drawings, Figure l is an elevation ot' an oil-cupembodying my invention. Fig. 2 is a sectional elevation of the same.

The oil-cup is of that class formed by using a glass tube, T, andconfining it between the metallic top C, rim R, and bottom B. The rim Ris made a part of the bottom B, and the top C is screwed to the rim It,thus contining the glass T between the metallic parts,"''a`nd creatingan oil-tight cup inside of the glass T, and between the top C and bottomB. Fig. 2 shows soft washers x and @,that intervene between the glassand the metal.

The top C is provided with an opening, I, into which the cap' la isscrewed. When k is removed the oil can be poured into the cup throughsaid opening I. The bottom part of the opening is provided with astrainer, t, which can be made of gauze or of perforated material, and Iplace in the center of the strainer an air-tube, b, which answers twopurposes. One is to let the air up out of the cup while oil is beingpoured in through the strainer t, and the other is that b can be used asa handle to lift the strainer out by when it requires cleaning. Thelower part of the opening I is provided with a small step orinternalbead, e, upon which the strainer can rest and be prevented .from fallingdown into the oilcup.

The second part of my invention consists in providing the rod or wire r,which is used with a disk-head, h, with a spiral Wire spring, s, madevery light and to rest upon the bottom B, and press up against the headh. The object of the spring s is to just support the weight of the wirer, so as to prevent its lower end, r', from wearing a groove in thejournal of the bearing to which the cup is attached. The'object of thedisk-head his to present a large surface, so that the oil and air in thecup will prevent the head h from bobbing up and down, so as to preventthe rod at r from being upset or battered against the journal, and sothat it will strike against the step e, and not hit the strainer t.

' What I claim as new is 1. The rod r, provided with the broad diskheadIL, in combination with the spring s, resting upon the base B, andsupporting the roda", `substantially as and for the purpose set forth.

2. The oil-cup consisting of the metal parts B R C k, and the glass tubeor vessel T, provided with the elastic Washers y, and having thestrainer t, tube b, rod r, provided with the broad head h, and spring s,arranged and operating substantially as described.
